Hi smpa01 

 

It seems javascript is not an official supported language in the code cell of Fabric notebook. And it's a challenge to pass a variable between Pyspark code cell and JS code cell.    

 

As an alternative, you may use Python to execute the JS code. Some python libraries provide the functionality to call Javascript from Python. This makes it easier to pass variables. 

 

I create a sample as below by using js2py. Create a function in JS, then call this function by Python. We can pass python variables to the JS function and get the result into another python variable. 

import js2py

get_pow = js2py.eval_js('function get_pow(a, b) {return Math.pow(a, b)}')
result = get_pow(10, 3)
print(result)
